      drm/imx: fixes and drm managed resources
      
      - Reduce stack usage in ipu-di.
      - Fix imx-ldb for compile tests.
      - Make drm encoder control functions optional.
      - Add drm managed variants drmm_encoder_alloc(),
        drmm_simple_encoder_alloc(), drmm_universal_plane_alloc(), and
        drmm_crtc_alloc_with_planes() for drm_encoder_init(),
        drm_simple_encoder_init(), drm_universal_plane_init(), and
        drm_crtc_init_with_planes(), respectively.
      - Update imx-drm to use the new functions for drm managed resource
        allocation, moving initialization from bind to probe where possible.
      - Fix imx-tve clock provider leak.

      Merge tag 'topic/dp-hdmi-2.1-pcon-2020-12-23' of git://anongit.freedesktop.org/drm/drm-intel into drm-next
      
      Add support for DP-HDMI2.1 PCON
      
      From the series cover letter:
      
      This patch series attempts to add support for a DP-HDMI2.1 Protocol
      Convertor. The VESA spec for the HDMI2.1 PCON are proposed in Errata
      E5 to DisplayPort_v2.0:
      https://vesa.org/join-vesamemberships/member-downloads/?action=stamp&fileid=42299
      The details are mentioned in:
      VESA DP-to-HDMI PCON Specification Standalone Document
      https://groups.vesa.org/wg/DP/document/15651
      
      This series starts with adding support for FRL (Fixed Rate Link)
      Training between the PCON and HDMI2.1 sink.
      As per HDMI2.1 specification, a new data-channel or lane is added in
      FRL mode, by repurposing the TMDS clock Channel. Through FRL, higher
      bit-rate can be supported, ie. up to 12 Gbps/lane (48 Gbps over 4
      lanes).
      
      With these patches, the HDMI2.1 PCON can be configured to achieve FRL
      training based on the maximum FRL rate supported by the panel, source
      and the PCON.
      The approach is to add the support for FRL training between PCON and
      HDMI2.1 sink and gradually add other blocks for supporting higher
      resolutions and other HDMI2.1 features, that can be supported by pcon
      for the sources that do not natively support HDMI2.1.
      
      This is done before the DP Link training between the source and PCON
      is started. In case of FRL training is not achieved, the PCON will
      work in the regular TMDS mode, without HDMI2.1 feature support.
      Any interruption in FRL training between the PCON and HDMI2.1 sink is
      notified through IRQ_HPD. On receiving the IRQ_HPD the concerned DPCD
      registers are read and FRL training is re-attempted.
      
      Currently, we have tested the FRL training and are able to enable 4K
      display with TGL Platform + Realtek PCON RTD2173 with HDMI2.1 supporting
      panel.

      drm-misc-next for v5.12:
      
      UAPI Changes:
      - Not necessarily one, but we document that userspace needs to force probe connectors.

      - video: Fix documentation, and a few compiler warnings.
      - Add devicetree bindings for DP connectors.
      - dma-buf: Update kernel-doc, and add might_lock for resv objects in begin/end_cpu_access.
      
      Core Changes:
      - ttm: Warn when releasing a pinned bo.
      - ttm: Cleanup bo size handling.
      - cma-helper: Remove prime infix, and implement mmap as GEM CMA functions.

      - Automatically use the atomic gamma_set, instead of forcing drivers to declare the default atomic version.
      - Allow using degamma for legacy gamma if gamma is not available.
      - Clarify that primary/cursor planes are not tied to 1 crtc (depending on possible_crtcs).
      - ttm: Cleanup the lru handler.
      
      Driver Changes:
      - Add pm support to ingenic.

      - Cleanup compiler and docbook warnings in a lot of fbdev devices.
      - Use the drmm_vram_helper in hisilicon.
      - Add support for BCM2711 DSI1 in vc4.

      - Use degamma instead of gamma table in omap, to add support for CTM and color encoding/range properties.
      - Rework omap DSI code, and merge all omapdrm modules now that the last omap panel is now a drm panel.
      - More refactoring of omap dsi code.
      - Enable 10/12 bpc outputs in vc4.
